creating a square matrix from a vector

["Walter R. Paczkowski" <dataanalytics@earthlink.net>]

Good morning,

I have a vector of, say, 6 numbers (1:6) that represents the upper
triangle of a square matrix that has 0 on the main diagonal.  I want
to create that matrix.  So, if my vector is 1:6, I want

0  1  2  3
1  0  4  5
2  4  0  6
3  5  6  0

How can I do this easily?  Any suggestions?  The actual vector
for my project has 325 elements so typing it in is not an
option.

Thanks for any help.
